I have just installed 12.5.1 on my iMac 5k i7, and there are several issues I keep experiencing. When working with audio, and keyframes there are random crashes, just completely shutting off resolve, when I'm trying to adjust, select or delete keyframes. Also when trying to delete clips in the timeline, it has now shut off (the program) several times. Also there are inconsistencies when trying to drag an audio keyframe left and right vs. up and down. a lot of the time i cannot drag left and right, ONLY up and down, but then after a few times it will work left and right,...very frustrating. Seems to be running faster all around, loading, playing, NR, effects, transitions, etc, but these crashes are happening very frequently, as in the last 1 hour I have had at least 6 crashes in Resolve 12.5.1. directly dealing with the audio keyframes.

Just so you know for the next patch, as this is obviously buggy currently.
